Advantages and Disadvantages of a Metal Steel Case for Your AR-15


A metal steel case has a few distinct advantages. Like brass, steel does not return to its original dimensions, which makes extraction a challenge. The steel case expands during ignition but fails to contract afterward, requiring the shooter to manually dislodge stuck cases. Because of these issues, many manufacturers coat steel cases with polymer or lacquer to reduce metal-on-metal friction. However, these coatings do not make steel cases as reliable as brass ones.
Although steel-cased ammo is not corrosive, it may be stored for long periods. Generally, steel-cased cartridges contain magnetic bullets and a bi-metal jacket that is almost 100% steel. Hence, steel-cased ammunition is suitable for long-term storage. For the sake of convenience, steel-cased cartridges can be easily stored in a telescoping magnetic box.

Although the steel-cased ammunition may be harder to wear on your gun, it is not significantly more durable than brass. Brass is the more expensive raw material, while steel costs a bit more to manufacture. But, steel is still a great option for your AR-15. And, while steel-cased ammo is not more expensive, it does cost a bit more than brass, so it's an excellent choice for most people.
Aside from its durability, steel-cased ammo is more difficult to extract than brass-cased ammo. In addition to the high cost of steel-cased ammo, you may be prone to malfunctions and longer cleaning times. Hence, if you find yourself stuck using steel-cased ammo, try switching to another brand. The extra effort you put into cleaning your gun will pay off in the long run. Check out the best case for ammos here:
Another disadvantage of a metal steel case is that it is not reloadable. It is also difficult to manipulate, so it might be more challenging for amateur reloaders. Furthermore, the coating on the steel casing is likely to wear off, which could cause high-friction cases. For these reasons, it is better to purchase brass-cased ammo instead of steel. This way, you can save money by reloading less frequently.
Another disadvantage of using steel-cased ammunition is its poor performance. Due to its hardness, it is more likely to tear brass casings, but some delayed blowback-operated weapons will run fine even with steel cases. A good example of this is the AK-pattern gun. The brass-cased ammo will corrode the gun and need to be replaced. If your gun does not run without any ammunition, it is a good idea to switch to brass.
